Oracle应用容器云的自由

在这篇博客文章中，我将介绍如何部署CloudEE封装在杜克大学应用自由尤伯杯罐子Oracle应用集装箱云端。

在Oracle Application Container Cloud中进行部署所需的部署工件是一个ZIP归档文件，其中包含应用程序über-jar和清单文件（manifest.json）。下面列出了CloudEE Duke的manifest.json的Liberty版本。

manifest.json

{
    "runtime": {
        "majorVersion": "8"
    },
    "command": "java -jar cloudee-duke.jar",
    "release": {
        "version": "1.0",
        "build": "1",
        "commit": "123"
    },
    "notes": "Dukes says hello from Liberty"
}

您需要指定供Liberty使用的端口。这可以通过使用环境变量$ {env.PORT}在server.xml中进行配置来完成，如下所示：

<server description="Sample Liberty server">
    <featureManager>
        <feature>microprofile-1.2</feature>
    </featureManager>
 
    <httpEndpoint  httpPort="${env.PORT}" 
                   httpsPort="9443"
                   id="defaultHttpEndpoint" 
                   host="*" />
 
    <quickStartSecurity userName="duke" userPassword="duke"/>
 
    <keyStore id="defaultKeyStore" password="Liberty"/>
</server>

über-jar是通过结合使用Maven资源插件和Liberty Maven插件来生产的：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.0.2</version>
    <executions>
        <execution>
            <id>copy-app</id>
            <phase>package</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/liberty/wlp/usr/servers/defaultServer/dropins</outputDirectory>
                <resources>
                    <resource>
                        <directory>${project.build.directory}</directory>
                        <includes>
                            <include>${project.build.finalName}.war</include>
                        </includes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>net.wasdev.wlp.maven.plugins</groupId>
    <artifactId>liberty-maven-plugin</artifactId>
    <version>2.2</version>
    <extensions>true</extensions>
    <configuration>
        <install>
            <type>webProfile7</type>
            <version>2018.+</version>
        </install>
        <configFile>${basedir}/src/main/liberty/config/server.xml</configFile>
        <serverEnv>${basedir}/src/main/liberty/config/server.env</serverEnv>
        <jvmOptionsFile>${basedir}/src/main/liberty/config/jvm.options</jvmOptionsFile>
        <packageFile>${project.build.directory}/${project.build.finalName}.jar</packageFile>
        <include>runnable</include>
    </configuration>     
    <executions>
        <execution>
            <id>install-liberty</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>install-server</goal>
            </goals>
        </execution>
        <execution>
            <id>package-app</id>
            <phase>package</phase>
            <goals>
                <goal>package-server</goal>
            </goals>
        </execution>
    </executions>               
</plugin>

有关如何使用maven命令生成可部署的ZIP归档的示例，请参见完整的pom.xml ：

mvn clean package assembly:single -Pliberty

这将在目标文件夹中生成一个名为cloudee-duke-oracle-liberty.zip的文件。这是您将部署到Oracle Application Container Cloud的ZIP存档，如下面的屏幕快照所示。

部署应用程序后，您应该可以访问hello端点

https://<dependsonyouraccount>.oraclecloud.com/helloZ

公爵说你好！

您还将拥有MicroProfile实施提供的运行状况和指标终结点

https://<dependsonyouraccount>.oraclecloud.com/health

{
结果：“ UP”，
检查：[]}
